The Lark LAC-15 Alumina Crucible 15mL is a high-performance laboratory vessel designed for extreme thermal environments and high-precision chemical analysis. Crafted from 99.95% high-purity alumina (Al₂O₃), this crucible is engineered to withstand temperatures up to 1800°C, making it an essential tool for material science, metallurgy, and advanced chemical synthesis. Its high-density, non-porous structure ensures excellent chemical inertness and minimal sample contamination, even when working with aggressive fluxes or molten metals.

Key Features Alumina Crucible 15mL

• Ultra-High Purity: The 99.95% alumina composition minimizes leaching and ensures high-purity results in analytical chemistry.

• Extreme Heat Resistance: Suitable for continuous operation at 1600°C and short-duration peaks up to 1800°C.

• Superior Hardness: With a Mohs hardness of 9, it offers exceptional wear and abrasion resistance.

• Non-Porous Surface: Features a smooth interior for easy sample recovery and resistance to chemical erosion from acids and alkalis.

• Precision Manufacturing: Specifically designed for uniform wall thickness to provide even heat distribution during firing.
